Application filed October 9, 1920, Serial No. 415,729.

T aZZ whom it may concern Be it knownthat I, lVILLIAM A. STUART, a citizen of the United States, residing at Tacoma, in the county of vPierce and State of lVashington, have invented new and useful lmprovements'in Water-Elevating Devices, of which the following is a specification.

This invention relates to water power machines andhas for its object the provision of adevice designed-tor liftingor forcing vater from streams and the like to points above gravity flow, such as highlands, reservoirs, pressure tanks, storage tanks or basins, and the like. v

An important and more specific object is the provision of a device for this purpose which is operated by water flow only, the device operating on the principle of the hydraulic'ram and being entirely automatic injoperation as long as water underislight heador-pressure is" fed to the device, the

device operating to expel forcibly a portion "of the water, the remainder of the water being otcourse wasted after its power is spent,

A' further object is the provision of a device of this character which is of sufii- 'cient power to "be of actual service in lifting water in sufficient quantities to render its efiiciency of value it being of course apparent "that the cost of operation is practically nil inasmuch as it is the waterhead alone which is employed as a motive force.

An additionalcbject is the provision of a device of this character which will becomparatively simple and inexpensive in -manufacture and 1nstalla't1on 'hi hl eflicientand v 3 b I powerful 1n use, durable in service, and a general improvement in the art.

\Vith the above and other objects and advantages in view, the invention consists in the details of construction to be hereinafter more fully described and claimed and illustrated in the accompanying drawings in which-- I i. f

Figure '1 is a side elevation of the complete device,

Figure '2is a plan view, r v Figure 3'1san endielevatlon, I Y Flgure 4 1s a vertical sectlonal vlew thro'ughone end ofthe machine on a larger scale,

V Figure 5 is a similar view taken at right angles to Figure 4,;

Figure 6 is an enlarged vertical sectional view through the lower portion of one end of the device and showing the valve mechanism in use, and k j v j The remaining figuresare detail lviews. f Referring more particularly-to the drawings, the numeral 10 designates a supporting frame which is tormedot any suitable material such as angle 'ironybars, or the like, and which may be of any desired height and of course of rigid construction. Mounted upon the top of this frame is a reservoir tank 11 which extends laterally besary that a constant current be supplied to the reservoir inorder to eti'ectoperation of the parts to be descrlbed. i a The numeral 12 designates the base 0 ed and rising from this base at Iopp'osite sidesof and spaced from the frame andprojecting ends of the tank 1l,are upright cylinders13 within each of which is operable a piston 14- carried by a rod 15; providedat its upper end with across head 16 vertically the device upon which the frame 10 is mountmovable between uides 1 At the, bottom which communicates with the lower end'i of the cylinder and which communicates with a pipe 19. The-pipes leading trom the two cylinders are connected to. a T 20 from of each cylinder 13 is a passage member 18 f which extends a discharge pipe21; Located v in the passage member adjacent its juncture with the pipe 19 is-a valveseat 22 "normally closed by a gravity valve 23 carried by' a stem 24 slidable through guides 25. Asuitable clean-out plug 26 is provided in'the passage member below the valve seat 22 whereby access maybe had for effecting adjustments or tor-cleanlng out accumulations.

Connected with the passage member -18;be

tween the cylinder 23 and valve seat 22is an upwardly inclined pipe 27 which-leads intolthe bottom of the reservoir tank 11.

Located at the lower/end otthe pipe 227 is a spider bearing '28 through which'tis slidable a stem 29 of a valve. 30 and connected with this stem isa flexible member 31 such as a cable or chain which extends upwardly beyond the top ofthe pipe'27 and which is connected with an adjustable eye bolt 32 carried by one end of a bar-33which is pivoted intermediate its ends upon a bracket 34 mounted upon the bottom of the,

tank 11. The other end of this bar 33 is notched, as indicated at 35, and mounted upon this end is a weight 36 having a tongue 37 engagable within any one of the notches 35. The purpose of this weight and bar is to counter-balance the valve and its associated parts so that the valve 30 will be normally held closed against a seat 38 at the bottom of the pipe 27 where the latter communicates with the passage member 18.

Journaled upon cross bars 89 of the frame 1.0 are walking beams 40 which carry at their ends tanks 41 and these tanks are connected in pairs by yokes 42 disposed outwardly of the cylinders 13. It is of course apparent that the connection of the walking beams with the tanks 41 must be pivotal so that the tanks 41 will remain always in horizontal position irrespective of the positions of the walking beams. These tanks extend partly below the projecting ends of the reservoir tank 11 in position to receive water discharged from the latter. At each end. the bottom of the tank 11 is provided with a pair of openings 43 immediately abovethe tanks 41 and each of these holes is normally closed by a flap valve 44 carried by a pivoted arm 45. Slidable through guides 46 on each end of the tank 11 are vertical rods 47 which extend downwardly below the tank a considerable distance and which are connected at their upper ends with the flap valves 44 by flexible members 48.

Formed in one end of each of the tanks 41 is an opening 49 normally closed by a valve 50 carried by links 51 and to which is connected a flexible member 52, such as 'a chain. or the like, which is also connected with a bracket 53 depending from the tank 11.

The operation of the device is as follows:

Initially, the device must be so arranged that the tanks 41 at one end of the device are in their highest positions engaging against the bottom of the tank 11. At this time and in fact at all times, the pipes 27 are full of water and the valves 30 are normally closed, being held in closed position by the weighted lever bars 33. When the tanks 41 at one side are in their uppermost positions, the bottoms of the tanks will engage against the lower ends of the rods 47 and move them upwardly which will'result inupward movement of the flap valves 44. The holes 43 in the bottom of the tank 11 will then be uncovered and the water within the tank will flow into these elevated tanks 41. When the tanks 41 fill they will gravitationally descend. carrying with them the piston rod 15 and the piston 14. At the sametime the tanks 41 at the other end of the device will be elevated and will engage the rods 47 and open the other flap valves 44 which will result in filling of the other tanks 41. At the time that the second mentioned tanks 41 are filling the first mentioned tanks 41 will have reached their lower positions whereupon the flexible member 52 connected with the bracket 53 will cause the valves 50 to swing upwardly, uncovering the openings 49 whereupon the water within the first mentioned tanks 41 will flow out through the openings 49. As the tanks 41 are connected by the connecting rods or links 41 with the cross heads 16 it will be seen that as either pair of tanks 41 moves upwardly the pistons 14 in the associated cylinders 13 will likewise be moved up wardly, whereupon the valves 23 will be closed and the valves 80 opened whereupon the water within the pipes 27 will flow into the passage members 18 and into the cylinders 13. When the pistons 14 reach the up,- per limit of their movement the weighted lever 33' will operate to reclose the valves 30. As the tanks 41 are filled and descend,

the associated pistons 14 will move downwardly whereupon the water within the cylinders 13 will be forced therefrom, through the passage members 18 and will unseat the valves 23 and pass out through the pipes 19 and out through the pipe 21 which leads to wherever the water is desired. This action is continuous as long aswater is supplied to the tank 11 and it is of course'apparent that the tanks 41 at both sides of the'machines will be alternately filled and emptied and the piston correspondingly actuated. In this way it will be seen'that water Wlll be constantly forced by the device to any deof course to be understood that I reserve the right to make such'changes in the form, con struction, and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claims.
